Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed April 5, 1905. Serial No. 253,926.

WELL, acitizen of theUnited States of Amer v ica, residing at Waukomis, in the county of Garfield and Territory of Oklahoma, have invented new and useful Improvements in Vehicle-Axles, of which the followingis a specification.

My invention relates to vehicle-axles and it'consists in the construction and. arrangement of parts, as will be hereinafter described,

and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of an axle embodying the invention. Fig. 2 is a detail transverse section taken on the line 2 2 of Fig. 1. Fig. 3 is a detail elevation showing a slightly-modified embodiment of the invention.

Referring to the drawings, 1 designates an' axle provided with detachable spindles ,2,

equipped at their outer ends with hub retain-j ing nuts 3, these arts,-except as hereinafter explained, being 0 the usual or any appropr'iateconstruction and material.

In accordance with my invention I form on the upper surfaces of the straight horizontal ends of the axle 1 non-circular tapered sockets 4, each of which in the form of device illustrated in Fig. 1 consists of a plurality of transversely-projecting spaced-apart vertical f upwardly-extended projections 5, provided with ing sizes an preferably of substantially rectangular form, as shown in Fig. 2, while the spindles 2 are provided at their inner ends with shoulders 7 and with arms or extensions 8, tapered throughout their length from their outer ends to their point of juncture with the shoulders 7, these extensions being of a crosssectional form corresponding to that of the socket 4. The outer terminal of each extension 8 is threaded for the reception of a plant-.

' ing-nut 9.

perforations 6 of relatively varyflanges 5 and the nuts 9 with the adjacent faces of the inner flanges composing the socket the spindle will be retained securely in place andendwise movement or thrust of the latter obviated, and, further, that owing to the socket and extension being of corresponding non-circular form in cross-section the spindle will be fixedly held against rotation relative to the axle. The central projections between the other or opposite projections serve to reinforce the central portions of the extensions, so as to render the spindle more rigid.

In Fig. 3 I have illustrated a slightly-modified embodiment of the invention, in which the construction and operation of the parts is identical with that above described, except that,tl1e walls of the socket 4 are made continuous throughout the length of the latter as distinguished from the skeleton form of socket illustrated in Fig. 1. Having thus described the invention, what is claimed as new is' V I The structure herein described comprising a bentaxle provided with straight horizon.- tal opposite ends, each having on its upper surface a plurality of vertical upwardly-extending projections arranged one after the other at suitable distances apart thereon, and each of the projections being provided with a decreasingtapered aperture or opening therein, a spindle having a decreasing tapered extension mounted in the tapered o enings of the projections, a collar arrange centrally between the spindle and extension, and a nut on the inner end of the extension serving to contact with the outer wall of the inner projection to permit the collar to contact with the outer face of the outer projection, each of the horizontal portions of the axle having a projection arranged centrally between the other or opposite projections which serves to reinforce the central portions of said extensions, substantially as specified.

- In testimony whereof I affix my signature in presence of two witnesses.
